I mean, if wine is a problem they did basically the same thing with the WSL, especially version 1 (version 2 is just a VM, but the concept of running unmodified Linux binaries on Windows like they are native application is the same).

I think that they don't care about going against the open soruce community, given that Microsoft uses a lot of open source software in their products (also, probably violates the terms of the GPL license of such software).
